C++ Program to Assign random values to a 2D array through "rand()" Function

/* As we are assigning random value during the run time, we just have to dynamically allocate the memory and use the pointer as a 2D array directly and assign random values to this 2D array. Here the memory allocated is only for the columns, now for the rows we just need a for loop and assign the value for every row a dynamic memory. We can use the pointer just the way we use a 2D array.*/

// Assigning random values to a 2D array
#include<iostream>
#include<iomanip>#include<stdlib.h>
using namespace std;
int main()
{
	int x = 3, y = 3;  //user can also ask these value during runtime

	int **ptr = new int *[x];

	for(int i = 0; i<y; i++)
	{
		ptr[i] = new int[y];
	}
	srand(time(0));

	for(int j = 0; j<x; j++)
	{
		for(int k = 0; k<y; k++)
		{
			int a = rand()%10;
			ptr[j][k] = a;
			cout<<ptr[j][k]<<" ";
		}
		cout<<endl;
